Excel 2003

Hi,
I have developed a simple result program in excel 2003. I have stuck up at the following point:

I have total seven subjects based on which I need to prepare a result. My aim is to find out failures. My condition is, if a student secures less than 35 marks out of 100 in more than two subjects, then in the Rem column Header "FAIL" should be displayed. Actually I need to find the count which gives me failures in more than 2 subjects. I have used Count(), but it doesn't work?
